[EXPLORER][RUNDLL32] Restore minimized non-task windows (#5228)

Browse source 
The minimized non-task windows were not usable due to the bugs. In some situations, the system will restore the minimized non-task windows.
- Add IsTaskWnd helper function.
- Add SendPulseToTray function to send a pulse to the tray window.
- At some shell hook handlings, send a pulse to the tray window.
- Add IgnorePulse flag to control the timing of restoring.
- Add a timer to reset IgnorePulse flag.
- If the pulse has come and IgnorePulse flag is false, then restore the minimized non-task windows.
- Modify the rundll32 window procedure.
- Use WINDOWPLACEMENT to restore the minimized windows.
